I sought of had issues and couldn’t complete the parts on the first boar(4x8ft MDF). Had to complete it on the one in the picture. Had a lot of chain-skipping issues… I had t re-align my left motor, then of course re-ran calibration… I also make my cuts in one single pass nice and clean(just remember to set tabs)… I hope you get inspired. Cheers to the inventors…

Thanks for the info. The rule of thumb I and others have been following was to cut not deeper than the diameter of your bit. Which of course makes it easier if you have a z-Axis motor and can automate it. You are cutting slower in x/y which maybe compensating for the depth.
